Archive for December, 2017

After a benign period of weather the past few weeks, things are about to change in a big way. By Thursday, December 7th, temperatures are expected to be well below normal here in the Mid-Atlantic States as a strong cold front will usher in much colder air. There is going to be a warmup prior to the front early in the week. A change in the upper-level wind configuration is expected to produce a large trough over the eastern half of the nation. This is a dip in the jet stream that will bring down colder air. For the last few weeks, the upper-level winds have been basically blowing west to east which resulted in a very quiet and dry weather pattern. Showers are expected to accompany the cold front as it moves through the region on Wednesday. This should be the first significant rainfall for the Hampton Roads area in several weeks. Areas well to our north and west may see some snowflakes as the precipitation ends. I checked the longer range projections and it appears as of now that temperatures are expected to remain at or below normal for quite some time in the Northeast and parts of the Mid-Atlantic States. Only time will tell whether that forecast is correct. There is a chance as the front stalls well to our south and east that a low pressure area will develop by the weekend bringing another period of rain but that is not a certainty as of now. So, enjoy the pleasant autumn weather this weekend and early next week! Thanks for reading and have a great weekend!
